I just did this on my '02 F-250 about a month ago. I ordered a Flowmaster catback system from Summit Racing, which replaced the entire system from that clamp you mentioned all the way back to the tip. The system was too short so I had to get a small piece of pipe made at a muffler shop to extend it, but other than that, it was a good experience. I was able to do it all with the truck on the ground, and I'm a pretty big guy. You will definitely need a helper, a breaker bar, a hacksaw, a big hammer, and a strong helper... But it's doable and a lot cheaper than paying a shop to replace it with stock stuff. My setup is not loud at all, just had a nice throaty tone. Feel free to PM me for more info.Posted via Mobile Device
